PLEASE HELP QUICKKK ITS DUE AT 12!!! An isosceles trapezoid is a quadrilateral with two congruent legs, a pair of parallel bases
lys-0071 [83]

Answer:

Trust me, I know my stuff.

Step-by-step explanation:

Use the diagonals to make two triangles. They will be the longest sides. We know two sides and an angle are congruent. By use of the Side Angle Side congruence conjecture, we know the triangles are congruent. Corresponding parts of congruent triangles are congruent, therefore, the diagonals must be congruent. Good luck.

What is the fourth term of the expansion of the binomial (2x + 5)^5?
Alik [6]
Ok, 1 bionimial theorem coming right up

for a binomial expansion of (a+b)^n
the kth term is
\left(\begin{array}{ccc}n\\k-1\end{array}\right)a^{n-(r-1)}b^{k-1}
\left(\begin{array}{ccc}n\\k-1\end{array}\right) means \frac{n!}{(k-1)!(n-(k-1))!}

n is 5
4th term
4-1=3
and a=2x
b=5
so
\left(\begin{array}{ccc}5\\4-1\end{array}\right)(2x)^{5-(4-1)}5^{4-1}
\left(\begin{array}{ccc}5\\3\end{array}\right)(2x)^{2}5^{3}
\left(\begin{array}{ccc}5\\3\end{array}\right)(2x)^{2}5^{3}
(10)(4x^2)(125)
5000x^2 is the 4th term
